1. FISH - In the FISH setting we put the tail of the fish towards the blocking wall / visible pin

2. FISH - Raise the ring and insert the tail of the fish until it is between the edge of the disc and the edge of the ring

3. FISH - We lower the ring by gripping the fish's tail


5. FISH – with one hand we hold the head of the fish and with the same hand we push the disc down,with the other hand we start scraping or filleting the fish

Thanks to that we keep the head and the tail of the fish with one hand at the same time.
